Final answer:
The incorrect method for examining for scoliosis is having the child squat down with hands extended forward. The proper assessment involves the child standing erect and bending forward to identify any abnormal curvature or twisting of the spine, which are signs of scoliosis.
Step-by-step explanation:
In an examination for scoliosis, the incorrect method listed is "the child should squat down with hands extended forward so the nurse can observe for asymmetry of the shoulder blades." This position does not effectively help in observing the signs of scoliosis. The proper method involves having the child stand erect and then bend forward with the back parallel to the floor while the nurse observes from the side for any unevenness or humps on the back, which are indicative of scoliosis.
When scoliosis is present, an individual will have challenges bending directly forward, and the right and left sides of the back may not level each other in a bent position. The abnormal lateral curvature of the spine in scoliosis is often accompanied by the twisting of the vertebral column, which can become pronounced during adolescent growth spurts. It is essential to note that while most cases of scoliosis do not require treatment, more severe cases might necessitate a back brace or surgery.
